It must be 1-ton brake season !! I just put my 47 1-ton in the air for a brake overhaul. My truck has sat for over 20 years but everything is original. Mine is a dually with the 18" rims. As soon as I could break the wheel cylinders free I will post some numbers. I have heard that my drums are very hard to find ans NO new pads are available ANYWHERE. Does the sleeving process deteriotate the stopping ability of the truck? I was thinking about just honing out the cylinders and rebuilding?
